Auto make Sync Gateway online after Couchbase Server restart

For some reason, my Couchbase Server will auto restart,and when my Couchbase Server is online, the SG will not notice the Couchbase Server is online, so when I make some request to SG,SG logs says:

2016-05-05T12:36:13.940+08:00 HTTP: #1265:     --> 503 DB is currently under maintenance  (0.0 ms)

I need to send this request to make SG online:

curl -X POST -H "Content-Type:application/json"

How can SG auto online after Couchbase Server restart.

Currently there’s no automated reconnect, although there’s a pending enhancement we’re tracking here:

OK, Thank you for replay. I will trace this enhancement.
